Dry needling is a technique that acupuncturists, physical therapists and other trained healthcare providers use to treat musculoskeletal pain and movement issues. It’s almost always used as part of a larger pain management plan that could include exercise, stretching, massage and other techniques. During this treatment, a provider inserts thin, sharp needles through your skin to treat underlying myofascial trigger points.

Trigger points are knotted, tender areas that develop in your muscles. These trigger points are highly sensitive and can be painful when touched. Sometimes, a trigger point may be near the location of your pain. But they’re also often the cause of referred pain. Referred pain is pain that affects another part of your body.

Physical therapists use needles to alleviate your trigger points. When dry needling is applied to your muscles and tissues, it can decrease tightness, increase blood flow and reduce local and referred pain. Providers use solid needles that don’t contain any kind of medication. This is why the technique is called “dry.”
